GeForce 8600 GT 1GB DDR2 vs GeForce GTX Titan

Intro

Compare those specs to the GeForce GTX Titan, which makes use of a 28 nm design. nVidia has set the core speed at 837 MHz. The GDDR5 RAM runs at a speed of 1502 MHz on this particular card. It features 2688 SPUs along with 224 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8600 GT 1GB DDR2		47 Watts
GeForce GTX Titan		250 Watts
	Difference: 203 Watts (432%)

Memory Bandwidth

The GeForce GTX Titan should theoretically be quite a bit faster than the GeForce 8600 GT 1GB DDR2 overall. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce 8600 GT 1GB DDR2		12800 MB/sec
	Difference: 275584 (2153%)

Texel Rate

The GeForce GTX Titan will be much (more or less 2070%) faster with regards to AF than the GeForce 8600 GT 1GB DDR2. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 8600 GT 1GB DDR2		8640 Mtexels/sec
	Difference: 178848 (2070%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX Titan is superior to the GeForce 8600 GT 1GB DDR2, and very much so. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 8600 GT 1GB DDR2		4320 Mpixels/sec
	Difference: 35856 (830%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
